Git Worktree for Issue Implementation

Set up an isolated git worktree with a new branch to implement a fix or feature for a GitHub issue.

Parse $ARGUMENTS to extract the branch name in format <category>/<issue-number>-<short-description>.

Branch Naming Convention

Branches must follow the pattern from CONTRIBUTING.md:

{category}/{ticket-id}-description-of-the-branch

Categories: feat, fix, exp, test, docs, keep (all lowercase, dashes, no underscores).

For feat and fix, a ticket number is mandatory.

Examples:

• fix/3562-clickhouse-drop-sync-perf
• feat/1234-add-new-destination

Steps

1. Parse and validate

Extract from $ARGUMENTS:

• branch_name: Full branch name (e.g., fix/3562-clickhouse-drop-sync-perf)
• category: Prefix before / (e.g., fix)
• issue_number: Number after / and before first - (e.g., 3562)
• short_name: Directory-friendly version: {category}-{issue_number}-{first-few-words} (e.g., fix-3562-clickhouse-drop-sync)

Validate the branch name matches pattern (feat|fix|exp|test|docs|keep)/[0-9]+-[a-z0-9-]+.

2. Verify the issue exists

gh issue view <issue_number> --json number,title,state

Warn if the issue doesn't exist or is closed, but continue.

3. Fetch latest devel

Fetch the newest devel from origin so the branch starts from the latest code:

git fetch origin devel

4. Create the worktree

Use /create-worktree skill:

/create-worktree <short_name> --branch origin/devel

Then create the feature branch inside the worktree:

git -C <worktree-path> checkout -b <branch_name>

5. Set up dev environment

Use /worktree-make-dev skill to set up the development environment in the worktree. This runs make dev and copies secrets.toml.

Note which secrets source was used — this determines what destinations can be tested.

6. Verify cwd

After dev setup, verify the cwd is still in the worktree:

pwd

If pwd does not show the worktree path, run cd <worktree-path> and verify again. Stop with an error if the cwd cannot be set.

7. Report

Report the worktree info and available test destinations:

Worktree ready: <worktree-path>
Branch: <branch_name> (based on origin/devel)
Issue: #<issue_number> - <issue_title>

Include the test credential availability from /worktree-make-dev output — downstream skills need this to know which destinations can be tested.
